Avast Secure Browser is a Chromium-based web browser for macOS built around aggressive tracking prevention, ad blocking, and anti-fingerprinting controls that most mainstream browsers leave switched off by default.
What is Avast Secure Browser?
Avast Secure Browser is a free, privacy-hardened browser from the cybersecurity company Avast, layering built-in protections on top of the Chromium engine that powers Google Chrome. Where Chrome ships with privacy features that are largely opt-in and modest, Avast Secure Browser flips the default: ads are blocked, trackers are silenced, and browser fingerprinting attempts are actively spoofed before you've touched a single setting.
The result is a browser that feels immediately familiar to anyone who has used Chrome — the same extension ecosystem, the same tab muscle memory — but with a meaningfully different threat posture out of the box.
What does Avast Secure Browser do best?
Its strongest suit is the breadth of protection it bundles without requiring you to hunt down extensions. I've run it alongside Brave and Firefox with uBlock Origin, and Avast's Bank Mode stands out as genuinely useful: it opens a locked-down window with its own process isolation specifically for financial sites, refusing to let other tabs or clipboard sniffers observe what's happening. That's a level of intentional design you don't get from simply installing a content blocker on Safari.
- Built-in ad and tracker blocking — no uBlock Origin download needed; works immediately at install
- Anti-fingerprinting engine — randomises or masks canvas, WebGL, and font enumeration signals that trackers use to follow you across sites
- Bank Mode — isolated browser process for sensitive transactions, with overlay-attack protection
- Webcam and microphone guards — visual indicators and quick toggles; more transparent than Chrome's permission bubble
- Hack Check — checks your email against known breach databases directly from the browser toolbar
Is Avast Secure Browser free?
Yes — Avast Secure Browser is free to download and use with no subscription required. The core privacy and security suite ships without a paywall. Avast does surface its paid VPN service (Avast SecureLine) inside the browser as an optional add-on, but every protective feature I've actually relied on day-to-day costs nothing.
Who should use Avast Secure Browser?
It fits best between two camps: users who want more protection than Safari or Chrome offer but don't want the configuration overhead of hardening Firefox from scratch, and Windows converts who are already familiar with Avast's security suite and want that same philosophy on their Mac.
I'd particularly recommend it to anyone who regularly does online banking on a shared Mac, handles client data in a browser, or is simply tired of being served ads that know exactly what they were googling twenty minutes ago. Power users who already have a bespoke Brave or Arc setup with carefully tuned extensions probably won't find enough marginal gain to switch — Brave in particular overlaps heavily on the fingerprinting and ad-blocking front and carries less brand baggage.
How does Avast Secure Browser compare to Brave?
Both browsers build privacy defaults on top of Chromium, and an honest comparison has to acknowledge they're more alike than different. Brave's Shields system is arguably more transparent — you can see exactly what was blocked per page with a single click — and Brave Rewards and its crypto integrations give it a distinct identity. Avast Secure Browser counters with Bank Mode and the tighter tie-in to Avast's broader threat-intelligence network, plus a somewhat less opinionated UI for users who just want a private browser and not a Web3 on-ramp. For Mac users who have no interest in crypto but do a lot of financial browsing, Avast edges ahead. For privacy enthusiasts who want granular control, Brave or a hardened Firefox still leads.
What are the best Avast Secure Browser alternatives?
The honest shortlist: Brave for the most comparable built-in blocking with arguably better transparency; Firefox with uBlock Origin for maximum extension flexibility and an open-source stack; Safari for the deepest Apple Silicon integration, lowest battery draw, and Intelligent Tracking Prevention (though its ad blocking is weaker); and Arc if you want a radically reimagined tab/sidebar interface. None of them ship Bank Mode, which remains Avast Secure Browser's most practical differentiator on macOS.
